Instructions for use of air receiver
1 This vessel can contain pressurized air; be ware of its potential danger in case of misuse.
2 The vessel shall only be used to store compressed air and shall not be subject to rapid fluctuation
of pressure.
3 This vessel shall only be used within the pressure and temperature limits stated on the data plate
and the testing report, which should be kept with care.
4 No alterations shall be made to this vessel by welding, drilling or any other mechanical methods
without written permission of the manufacturer.
5 Make sure that the vessel is complete with suitable and appropriate safety and control fittings and
replace them with new Atlas Copco ones (consult the parts list) if necessary.
The safety valve must be fitted directly to the vessel and the discharge capacity should be higher
than the air intake of the compressor. It should be set and leaded at a pressure of 11 bar.
6 Do not store the vessel near heating sources and inflammable substances and avoid storage of
the vessel in badly ventilated rooms.
7 Use vibration dampers to reduce the vibration during operation, which can cause failure.
Do not mount the vessel to the ground or fixed structures.
8 Drain condensate from the vessel daily, to prevent corrosion inside the vessel. During
maintenance, every 12 months, check for the presence of internal corrosion. Check more
frequently if the vessel is used with an oil-free compressor or when it is used in adverse conditions
(high humidity, presence of acids).
If corrosion is present, the minimum thickness is 3.45 mm for the shell and 3.4 mm for the head.
The legal checks have to be made in accordance with the local laws and rules where the vessel is
used.
